* The diffusion coefficient is the "weighted average" mutual diffusion coefficient interpreted on basis of Fick's 1st & 2nd Laws.
** E modulus strength retention after 6 months of exposure [sample thickness 400 micrometer].
For materials that show slow chemical degradation the retention does not become stationary.
